Title: Hand held electronic calculator
IPC: G06F15/02
Filed: 1990-10-01
Abstract: A portable electronic computer for conducting fraction calculations has a display including a first multiple-digit display area for displaying the numerator of a fraction, and a second multiple-digit display area for displaying the denominator of the fraction.  The numbers of digits of the numerator and denominator of a fraction to be displayed are obtained.   The number of digits of the numerator is compared with the number of digits of the denominator.  The difference between the number of digits of  the  numerator  and  the  number  of  digits  of  the denominator is calculated.  When the number of digits of the numerator is smaller than the number of digits of the denominator,  the  numerator  is  displayed  on  the  first display area with its position shifted to an upper digit place according to the difference.   When the number of digits of the denominator is smaller than the number of digits of the numerator, the denominator is displayed on the second display area with its position shifted to an upper digit place according to the difference.

Abstract: Process in manufacturing paper wherein stock is prepared using cellulose fiber material which contains calcium sulfate (gypsum), said material being disintegrated in an aqueous medium in order to form part of the stock for the paper to be pro-duced. The characterizing feature of the process is that (a) carbonate ions and/or hydrogen carbonate ions (CO32- or resp. HCO3-) are supplied to the aqueous medium, and (b) the pH in the aqueous medium is adjusted to an alkaline value so that calcium carbonate precipitates and forms part of the suspension. There are overall major advantages provided by the pro-cess in the context of applying gypsum coatings on paper, inasmuch as broke can be reused in the process without any trou-blesome gypsum precipitation. Moreover a new grade of coated paper is described, the characterizing feature of this paper being that the filler of the base paper consists entirely or partly of precipitated calcium carbonate (PCC) and that the pig-ment of the coating layer consists entirely or partly of calcium sulfate.
